Answer:

-30

Step-by-step explanation:

y = -10x is a function that can also be represented by f(x) = -10x. We are to evaluate this function at x = 3. To do this, replace both instances of x in this function by 3 and simplify the result:

f(3) = -10(3) = -30

Answer:

y= -30

Step-by-step explanation:
